IQUST AND WEATHER PROOFING CONSTRUCTION.

Specification of Letters Patent. Patented Mar. 16, 1915 Application filed August30, 1912. Serial No. 717,846.

certain new and useful Improvements in Dust and Weather Proofing Constructions; and I do hereby declare that the following'is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numbers of reference marked thereon, which form a part of this specification.

This invention relates to improvements in weather and dust proofing devices for windows and the like.

Heretofore many difierent arrangements and constructions have been devised and tried for the purpose of excluding dust and weather from sliding windows. These are frequently expensive to apply, and short lived in operation, and, in some instances involve and include a multiplicity of parts, detracting from their utility, and rendering the same likely to prove inefiicient.

The object of this invention is to provide a weather and dust proofing device adapted for use on sliding sash of any kind and for other purposes, and acting positively to exclude dust and moisture.

It is an object of the invention to afford a construction adapted to be installed at low cost, and adapted for use for long periods of time without the likelihood of deterioration. or injury.

It is also an object of the invention to aiford a device of the class described adapted for use in installations of any kind for the purpose of excluding dust, and adapted for application by one not having previous experience or skill in the art.

I have shown my invention embodied in connection with an improved window frame construction, but it is to be understood that the devices may be applied to sliding windows in window frames of the usual or of any desired construction' llhe invention (in a preferred form) is illustrated in the drawings, and hereinafter more fully described.

In the drawings: Figure 1 is a fragmentary vertical section of a window frame and the sash therefor, showing the same equipped with devices embodying my invention. Fig. 2 is a transverse section of one side thereof. Fig. 3 is a sectional view of the weather strip or guard for the top of the upper sash. Fig. 4 is a similar view of the weather guard strip for weather proofing the space at the meeting rails of the sash. Fig. 5 is an end elevation of the weather proofing strip. for use on the bottom rail of the lower sash.

In the drawings: 1, indicates the jamb of the window frame; 2, the blind stop; 3,.

the parting strip; 4, the inner stop; 5, the sill, and 6, the sub-sill. In the construction shown, the jamb l, is rabbeted for a width corresponding with the thickness of the parting strip, and also the thickness of the lower sash, and the parting strip 3,

secured therein, is made integral with a strip or batten 7, which fits in said rabbet, and.l which aifords the guide for the lower sas Secured on the sides of both sashes, and at the top of the upper sash, is a dust proofing member, comprising a strip of sheet metal bent to afford a web 8, to engage along the top and sides of the sash, and a flange 9, to engage along the outer side of said sash, and an outwardly bent flange 10, to fit in a groove or space therefor between the jamb and the parting strip 3, and between the inner edge of the batten 7, and the inner stop 4, respectively. Said flange 10, as shown, at its extremity is bent or doubled back upon itself affording a web or plate 11, adapted for attachment to the inner face of each sash, and to afiord a wear member against the outer face of the parting strip 3, and stop 4, respectively, thus affording a smooth bearing surface around the top and sides of the upper sash. The flange 10 on the upper and lower sashes respectively, projects into the groove or the batten or strip 7, and the outer stop to effectively seal the sides of the sash in the frame.

Secured along the top of the lower sash,

as shown in Fig. 1, is a strip of metal bent to afford a web 12, and a downwardly directed Fig. 1, and at its outer extremity is bent or turned downwardly and inwardly to afford an inclined wall 14, which, at its inner extremity, is bent downwardly to afford the integral attaching plate 15, which lies along the outer side of the meeting rall for the lower sash.

The projection afforded by the extra width of the web 12, and the inclined wall 14, of said dust proofing strip, affords suflicient resiliency to insure a yielding engagement upon the meeting rail for the upper sash when both sashes are closed, as shown in Fig. 1, to effectively exclude'dust and moisture. Substantially the same construction is employed upon the bottom rail of the lower sash. In this instance, the web 16, is of a width corresponding approximately with the thickness of said lower rail, and is bent upwardly to afford a plate 17 lying along (and, if preferred, recessed slightly into) said lower rail at its inner face, and bent outwardly to afford a flange 18, extending over the sub-sill, the edge of said flange being turned downwardly and rearwardly to afford a spring closing strip 19, which bears upon the sub-sill when the window is closed, affording a yielding contact, and effectively sealing the window. The outer edge of the plate or web 16, is also bent downwardly at a right angle to afford the flange 20, which is adapted to extend downwardly over the shoulder in the sill, and at its extremity is turned upwardly to afford an attaching plate 21, adapted to be secured to the outer face of the sash, and, if preferred, recessed slightly therein.

The operation is as follows: The side members of the dust proofing strip, whether at the side, top or bottom of the sash, may be recessed in the face of the sash to be finished flush therewith. When in use, the outwardly directed tongue or flanges on said weather strips project into suitable grooves or recesses therefor in the frame and seal against positive shoulders or walls afi'orded there-' for in the frame or afforded by the respective stops of the frame, and positivel seal the joints between the sash and the rame. The weather proofing strips for the bottom of the lower sash, and for the meeting rails of the sash, are provided with a resilient flange or. member adapted to positively engage when the sash are closed, to exclude dust and moisture, such engagement being of a nature, however, as to preclude injury to the finish of the woodwork under any conditions. If desired, a resilient contact member, such as 19, shown in Fig. 5, or 14, shown in Fig. 4., may be provided for waterproofingthe top of the upper sash. Ordinarily, however, this is not essential, and for convenience of illustration, has not been shown.

Of course, details of construction may be varied without departing from the principles of this invention.

It is to be understood, of course, that weather proofing devices such as described, may also be used on hinged doors, if desired, and it is evident that the same weatherproofing device may be employed for numerous other'purposes, and I do not desire to limit the patent granted on this invention to use in relation to windows only.

I claim as my invention:

In a device of the class described, the combination with a sliding sash therein, of a JOHN B. GLOWACKI. Witnesses:
